The history of the Great Warming of a half millennium ago suggests that we may yet be underestimating the power of climate change to disrupt our lives todayand our vulnerability to drought, writes Fagan, is the silent elephant in the room.

In 1990, Peter Larson, with his team of commercial fossil hunters from the Black Hills Institute, discovered the most complete Tyrannosaurus Rex specimen in history. He dubbed it "Sue" after the field paleontologist who first saw it sticking out of a sandstone cliff on the ranch of Maurice Williams, a Cheyenne River Sioux Tribe member in South Dakota's badlands. Because the skelton was 90% complete, its study promised to yield up priceless information on the life and habits of the T Rex.

At various times in a span of fifteen years, John McPhee made geological field surveys in the company of Eldridge Moores, a tectonicist at the University of California at Davis. The result of these trips is Assembling California, a cross-section in human and geologic time, from Donner Pass in the Sierra Nevada through the golden foothills of the Mother Lode and across the Great Central Valley to the wine country of the Coast Ranges, the rock of San Francisco, and the San Andreas family of faults.

The Gilded Age is the collaborative work of Mark Twain and Charles Dudley Warner that satirized the era that followed the Civil War. This period is often referred to as the “Gilded Age” because of this book. The corruption and greed that was typical of the time is exemplified through two fictional narratives: one, of the Hawkins, a poor family from Tennessee that tries to persuade the government to purchase their seventy-five thousand acres of unimproved land.

The great unknown of the Southwest is conquered by a one-armed man and his crew of adventurers, placing the Colorado River and the Grand Canyon on the map of the American continent. It is a journey no human being had ever made before. Dangerous rapids, narrow canyon walls offering no escape, terrifying river waterfalls, capsized boats, near drowning, lost equipment and disillusioned men are dramatically described by John Wesley Powell, leader of this adventurous party.

The aurora borealis, often referred to as the Northern Lights, is a natural light-show that appears in the sky around the north magnetic pole. Auroras can sometimes be seen in other places of the world, but not as clearly. In the southern hemisphere, the phenomenon is called "aurora australis".

In Powering the Future, Nobel laureate Robert B. Laughlin transports us two centuries into the future, when we’ve ceased to use carbon from the ground. Boldly, Laughlin predicts no earth-shattering transformations will have taken place. Six generations from now, there will still be soccer moms, shopping malls, and business trips. Firesides will still be snug and warm.

When Cinderella's stepmother prevents her from attending the Royal Ball, she gets some unexpected help. Here is the classic tale of a girl, her evil stepmother, and a pair of glass slippers that changes everything.

A highly entertaining and accessible introduction to our planet from the best-selling author of Schrödinger's Cat, The Scientists, and In Search of the Multiverse. In this incredible expedition into the origins, workings, and evolution of our home planet, John Gribbin does what he does best: takes four and a half billion years of mind-boggling science and digs out the best bits. From the physics of Newton and the geology of Wegener, to the environmentalism of Lovelock, this is a must-listen for Earth's scientists and residents alike.

In this well-informed and hard-hitting response to the scaremongering of the climate alarmists, Nigel Lawson, former Chancellor of the Exchequer and Secretary of State for Energy, argues that it is time for us to take a cool look at global warming. Lawson carefully and succinctly examines all aspects of the global warming issue: the science, the economics, the politics, and the ethics.

Produced by Climate Central — a highly regarded, independent, nonprofit journalism and research organization founded in 2008 — and reviewed by scientists at major educational and research institutions the world over, Global Weirdness summarizes, in clear and accessible prose, everything we already know about the science of climate change. It explains what is likely to happen to the climate in the future and lays out in practical terms what we can and cannot do to avoid further shifts.

Over the past few years, devastating tsunamis off the coast of the Indian Ocean have killed hundreds of thousands of people. Even more alarmingly, scientists predict that these tsunamis, as well as a series of earthquakes and volcanic eruptions, will be striking with even greater frequency and may eventually threaten Hawaii, California, and Oregon.

Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea. The presence of these early New World people was established by distinctive stone tools belonging to the Clovis culture. But are the Clovis tools Asian in origin? Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge the old narrative.

As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

A storm is a disturbed state in the atmosphere that causes severe weather. It may be marked by strong wind, thunder and lightning and heavy precipitation. This audiobook discusses different types of storms such as rainstorms, ice storms, and hurricanes.

The oceans cover 72 percent of the earth's surface, or 141,600,000 square miles. Ocean life comes in an enormous variety of sizes and shapes - from microscopic plankton to huge whales. This audiobook explores the oceans of the world and describes the types of plants and animals that can be found in them.

This audiobook describes different forms water can take in the atmosphere, including rain, snow, ice, and dew.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

Masterfully tying together history, science, and human drama, The Lost Dinosaurs of Egypt is the gripping account of two of the 20th century's great expeditions of discovery. In 1911 a German paleontologist found the remains of four entirely new dinosaurs in the Egyptian desert, but in a single night, all of his work was destroyed. Eighty-nine years later, an American grad student leads an expedition to unearth Stromer's dinosaur graveyard, and in doing so, he stuns the scientific world.

In this definitive guide, climatologists Barry D. Keim and Robert A. Muller examine the big picture of Gulf hurricanes - from the 1800s to the present and from Key West, Florida, to Mexico's Yucatan Peninsula - providing an extraordinary compilation and interpretation of the entire region's hurricane and tropical storm history. Drawing from their own research and from National Hurricane Center records, Keim and Muller examine numerous individual Gulf storms.
